Detailed explanation-1: -Soil pH is a measure of the acidity or alkalinity of the soil. A pH value is actually a measure of hydrogen ion concentration. Because hydrogen ion concentration varies over a wide range, a logarithmic scale (pH) is used: for a pH decrease of 1, the acidity increases by a factor of 10.

Detailed explanation-2: -Soil pH meters are devices used to measure the acidity or alkalinity of a soil. They work by measuring the hydrogen ion activity and this is expressed through the potential for hydrogen or ‘pH’. The pH scale ranges from 0 – 14 with 0 being extremely acidic, 7 being neutral and 14 being alkaline.

Detailed explanation-3: -Types of Soil Acidity Soil acidity determined by pH measurement during a routine soil test is known as active acidity. This is the concentration of H+ ions in the soil solution when measured in a 1:1 soil-to-water ratio mixture.

Detailed explanation-4: -Dig for a Sample. Using a hand trowel, dig four to six inches below the soil surface to obtain a soil sample. Collect the Soil. Place one to three teaspoons of soil in a clean glass. Pour in Distilled Water. Agitate the Soil. Drain the Sample. Use the pH Test Strip. Repeat the Process. 24-Apr-2022
